Social Bonding or Risky Habit? The Real Story Behind Alcohol

The idea that drinking helps people connect began to stir interest many years ago when a psychologist set out to study how alcohol affected stress and heart rate.
At that time, most experiments only involved men, so the researcher invited five young women to participate and measure how their bodies reacted to a drink.

Initially, the women kept quiet, but as they took sips, conversation flowed and laughter filled the room.
After an hour, their interaction had shifted from formal to friendly, illustrating how alcohol can loosen social barriers.

When new federal health guidelines were released this winter, a senior medical official mentioned that alcohol can bring people together.
The updated rules suggest Americans should drink less for better health, but they no longer specify a daily limit of one drink for women and two for men.
This change follows evidence that even small amounts of alcohol may increase risks such as cancer.
